We love Live CDs, but it’s a hassle installing the same packages every time you need to do a virus scan or recover accidentally deleted data. We’ll show you how to roll your own Ubuntu Live CD, with all the packages you want, and even more nice customizations.
The tool that we’re going to use is called Reconstructor, which is a free webapp that lets you roll your own Ubuntu and Debian CDs.

Getting Started
The first step, as noted above, is to sign up for an account. Click the Sign Up link and fill out the form that appears.
You will be greeted by Reconstructor’s main interface. To create your customized Ubuntu CD, click on the Create Project button in the left column.
Windows 7 uses a feature called homegroup, which enhances the workgroup feature in order to make home networking easier for all Windows 7 computers. However, this feature doesn’t work on Linux or older version of Windows. In order to connect your Linux computers to Windows 7 computers and share files and folders, you need to make a series of settings. First, it is to change the workgroup, so that all computers belong to one workgroup. In this tutorial I will demonstrate how to configure and change the workgroup on an Ubuntu PC.
